PyCharm 2016.2 Help

Opening Multiple Projects

Basics

PyCharm allows you to work with several projects simultaneously. So doing, PyCharm suggests the following
options:

Each project is opened in its own window. The
projects are independent, and cannot share information, except for the Clipboard operations. All the
projects run in the same instance of PyCharm and use the same memory space.

A newly opened project shares the same window as the already opened one. So doing, the project that has
already been opened, is considered the primary project, and is always shown first in
the Project tool window. All the other projects are added to the primary project.

Symbols from the added projects are visible from the primary one, but not vice versa.

Prerequisite

Make sure that one of the options Open project in a new window or
Confirm window to open project in
in the System Settings page of the Settings/Preferences dialog is selected.

Opening multiple projects

To open multiple projects, follow these steps

Open a project, while another one is already opened. PyCharm
prompts you to select whether you want to open the project in a new window, or reuse the existing window.

Do one of the following:

Click Open in new window button to leave the current project in its window and
open the new one in a separate window.

Click Open in current window, and select the check box Add to currently
opened projects.
The new project opens in the project tree, and adds to the currently opened project. So doing, the
project that has already been opened, is the primary project.

Clicking Open in current window without selecting the check box
Add to currently opened projects results in closing the current project and
opening the new one in the same window.

Deleting a project from view

If you want to close a project that has been added to the currently opened one (primary project), follow these
steps:
